   <p>如果您需要使用集群高可用特性，请先参考本节操作，为主节点添加内部通信网络平面，用于备份集群各节点通信。</p>
   <div class="section">
    <h4 class="sectiontitle">前提条件</h4>
    <ul>
     <li id="ZH-CN_TOPIC_0000001792342934__li26601649133316">配置集群高可用前，请确保已在DeviceManager界面为每个节点设置NTP自动同步，具体操作请参见《管理员指南》中的“配置设备时间”章节。</li>
     <li>主节点内部通信网络平面需要至少预留2个IP地址。</li>
    </ul>
   </div>
   <div class="section">
    <h4 class="sectiontitle">注意事项</h4>
    <ul>
     <li>添加主节点内部通信网络平面后，将导致系统重启，可能导致备份任务失败。</li>
     <li>内部通信网络平面添加完成，且已添加成员节点后，内部通信网络平面不支持修改，请谨慎操作。</li>
